This Drawing Shows the Plan of Arc

This article is almost diagrams or drawings. For artistic drawing, see Drawing. For other types of plans, see Plan (disambiguation).

Plans are a set of drawings or two-dimensional diagrams used to depict a identify or object, or to communicate building or fabrication instructions. Ordinarily plans are drawn or printed on paper, but they tin take the grade of a digital file.

Plans are used in a range of fields: architecture, urban planning, landscape architecture, mechanical technology, civil engineering, industrial technology to systems technology.

The term "plan" may casually be used to refer to a single view, canvas, or cartoon in a set of plans. More than specifically a programme view is an orthographic projection looking down on the object, such as in a floor plan.

Overview [edit]

Plans are often for technical purposes such as compages, engineering, or planning. Their purpose in these disciplines is to accurately and unambiguously capture all the geometric features of a site, building, product or component. Plans can also exist for presentation or orientation purposes, and are oftentimes less detailed versions of the former. The terminate goal of plans is either to portray an existing place or object, or to convey enough data to let a builder or manufacturer to realize a design.

The process of producing plans, and the skill of producing them, is frequently referred to equally technical drawing. A working cartoon is a type of technical cartoon, which is function of the documentation needed to build an engineering production or architecture. Typically in architecture these could include civil drawings, architectural drawings, structural drawings, mechanical drawings, electrical drawings, and plumbing drawings. In applied science, these drawings bear witness all necessary data to manufacture a given object, such as dimensions and angles.

Plan features [edit]

Format [edit]

Plans are frequently prepared in a "set". The set includes all the information required for the purpose of the prepare, and may exclude views or projections which are unnecessary. A set of plans can exist on standard office-sized paper or on large sheets. It tin be stapled, folded or rolled equally required. A set of plans can also take the grade of a digital file in a proprietary format such as DWG or an exchange file format such as DXF or PDF.

Plans are often referred to equally "blueprints" or "bluelines". Nonetheless, the terms are apace becoming an anachronism, since these copying methods have generally been superseded past reproduction processes that yield blackness or multicolour lines on white paper, or by electronic representations of data.

Scale [edit]

Plans are usually "calibration drawings", significant that the plans are drawn at a specific ratio relative to the actual size of the identify or object. Various scales may be used for different drawings in a set. For example, a floor programme may exist fatigued at 1:48 (or one/iv"=1'-0") whereas a detailed view may be drawn at one:24 (or one/ii"=1'-0"). Site plans are frequently fatigued at 1" = 20' (1:240) or one" = 30' (ane:360).

In the metric organization the ratios unremarkably are 1:v, 1:10, 1:xx, 1:l, i:100, 1:200, 1:500, 1:1000, i:2000 and 1:5000

Views and projections [edit]

Symbols used to define whether a projection is either Third Angle (right) or First Angle (left).

Considering plans stand for three-dimensional objects on a two-dimensional plane, the use of views or projections is crucial to the legibility of plans. Each projection is achieved by bold a vantage point from which to run across the place or object, and a type of projection. These project types are:

Nomenclature of Plan (drawing) and some 3D projections

• Parallel projection
  • Orthographic projection
    • Multiview projection, including:
      • Plan view or floor programme view
      • Elevation, ordinarily a side view of an outside
      • Section, a view of the interior at a detail cutting plane
    • Axonometric projection, including:
      • Isometric projection
      • Dimetric project
      • Trimetric projection
  • Oblique projection, and
• Perspective projection, including:
  • 1-point perspective
  • Two-signal perspective
  • Iii-bespeak perspective

Planning approach [edit]

In that location is no universal standard for sheet social club, however the following describes a common approach:

• Full general Data : The beginning sheets in a fix may include notes, assembly descriptions, a rendering of the project, or simply the projection title.
• Site : Site plans, including a key plan, appear before other plans and on smaller projects may be on the first canvas. A project could require a landscape plan, although this tin can be integrated with the site plan if the drawing remains clear.
• Specific plans : Floor plans, starting with the lowest flooring and catastrophe with the roof plan unremarkably appear near the showtime of the set. Further, for example, reflected Ceiling Plans (RCP)s showing ceiling layouts appear after the flooring plans.
• Elevations : Starting with the principal, or front end meridian, all the building elevations appear after the plans. Smaller residential projects may display the elevations earlier the plans. Elevation details may appear on the same sheets as the building elevations.
• Sections: Edifice sections that depict views cut through the entire building appear next, followed past wall sections, so detail sections.
• Details: Details may appear on whatever of the previous sheets, or may exist collected to appear on detail sheets. These details may include structure details that testify how the components of the building fit together. These details may also include millwork drawings or other interior details.
• Schedules: Many aspects of a building must exist listed as schedules on larger projects. These include schedules for windows, doors, wall or floor finishes, hardware, landscaping elements, rooms, and areas.

Where additional systems are complex and crave many details for installation, specialized additional plan drawings may be used, such every bit:

• Structural: While smaller projects may just show structural information on the plans and sections, larger projects accept split up sheets describing the structure of the edifice.
• Mechanical: Mechanical drawings bear witness plumbing, heating, ventilation and air-conditioning systems, or fire protection systems.
• Electric :Electric program drawings may include equipment and cable tray layout, lighting and ability, grounding, telephone, local area network, special communications or signal systems, or a reflected lighting plan.
